My dear Doctor*. 
Thank you for your letter of July 2rd, I expect 
the fourth set of Hitchcock's Guiana plants is q.^ite as well left 
with you as it would he at Washington, I have been so much occupied 
with my own Trinidad collection that I have not had time to overhaul 
Hitchcock's material at all yet, but will have it organized during 
the summer and named up along the lines you suggest. Yes, we should 
like to have a copy of the list of determinations you have made, and 
we will send you a list of whatever we can name here. Pennell can 
do the Sorophulariaceae as you suggest; I will do the sedges; Small 
will do Malpighiaceae; Barnhart will do Lentibulariaoeae; and there 
are various other small families that we can take care of. 
I am likely to have to go to Europe in August, and thought l 
would like to take along some of this northern South American material 
for comparison with named material at Kew, in order to help the Job 
a little to that extent. 
Yes, if you will send the Trinidad collection made by Johnston 
along I will look it over right away and return it to you. 
Yours faithfully 
Direct or- in-Chlef
